    ABSTRACT

    Objective:

    To traslate and validate of the Brazilian version of the SDI-2.

    Methods:

    This was a cross-sectional study. The cultural adaptation considered the stages of initial translation, synthesis of translations, evaluation by a committee of experts from different regions of Brazil, back-translation, and pre-test. The content validity and psychometric proprieties was assessed.

    Results:

    Ten specialists participated in the cultural adaptation of the SDI-2. The content validity showed a Content Validity Ratio (CVR) ≥ 0.75 (p = 0.05). A total of 674 subjects participated in the field study. The Exploratory Factorial Analysis (EFA) presented factor loads ≥ 0.445, and commonalities ≥ 0.40; and two dimensions represented 77% of the total variance explained. The Confirmatory Factorial Analysis CFA presented X2/df = 4.265; the Root Mean Square Error of Approximation RMSEA = 0.110; the Non-Normed Fit Index NNFI = 0.946; the Comparative Fit Index (CFI) = 0.963; the Goodness of Fit Index GFI = 0.986; and the Adjusted Goodness of Fit Index AGFI = 0.979 for a two-factor model. The coefficient values for the total SDI-2 score were 0.91 for Cronbach's alpha, 0.91 for McDonald's Omega, and 0.97 for the Greatest Lower Bound GLB coefficients. The invariance between sexes was 0.01 for the ΔCFI and ΔRMSEA, showing model stability for these two populations.

    Conclusion:

    The Brazilian version of the SDI-2 is self-report, valid, reliable and invariant across sex.

    Abstract

    Objective

    To validate the six-item female sexual function index (FSFI-6) in middleaged Brazilian women.

    Methods

    Cross-sectional observational study, involving 737 (premenopausal n = 117, perimenopausal n = 249, postmenopausal n = 371) Brazilian sexually active women, aged between 40 and 55 years, not using hormonal contraceptive methods. The Brazilian FSFI-6 was developed from the translation and cultural adaptation of the Portuguese FSFI-6 version. The participants completed a general questionnaire, the FSFI-6, and the menopause rating scale (MRS). The validation was performed by AMOS 16.0 software (SPSS, Inc., Chicago, IL, USA) for a confirmatory factor analysis (CFA). The chi-square of degrees of freedom (χ2/df), the comparative fit index (CFI), the Tucker- Lewis index (TLI) and the root-mean-square error of approximation (RMSEA) were used as indices of goodness of fit. Cronbach α coefficient was used for internal consistency.

    Results

    The process of cultural adaptation has not altered the Brazilian FSFI-6, as compared with the original content. The CFA for the FSFI-6 score showed an acceptable fit (χ2/df = 3.434, CFI = 0.990, TLI = 0.980, RMSEA = 0.058, 90% confidence interval (90%CI) = 0.033-0.083, p ≤ 0.001) and a good reliability was established in FSFI-6 and MRS (Cronbach α = 0.840 and = 0.854, respectively). In addition, 53.5% of the sample had low sexual function.

    Conclusion

    The FSFI-6 was translated and adapted to the Brazilian culture and is a consistent and reliable tool for female sexual dysfunction screening in Brazilianmiddleaged women.
